Angles TUX and TUS
Explanation:
Supplementary angles are angles that add up to 180 degrees. Angles that are 180 degrees are called straight angles since they form a straight line. Now, let's see which angles form a straight line.
Angles TUX and TUS are the only angles forming a straight line, SUX. The other angle pairs don't form the straight lines SUX, SUXZ, or TUV.
